Two clamping plate that are flexibly connected are provided with a plurality of breach on the edge of arbitrary clamping plate, the breach on two clamping plate cooperates the formation line hole.
Preferably, described clamping plate are specially the clamping plate by the insulcrete preparation.
Preferably, also comprise insulation rubber tube, described insulation rubber tube is connected with arbitrary clamping plate.
Preferably, described two clamping plate are connected by the active connection part, also are provided with block ring on one of them clamping plate.
Preferably, described block ring is hinged by in turning axle and described two clamping plate one of them.
Preferably, described short clip comprises two round mouth folders, and an insulated wire;
Described insulated wire two ends connect respectively a round mouth folder.
Preferably, the upper cover of described round mouth folder has insulation sleeve, and the chuck of described round mouth folder is exposed to outside the insulation sleeve.
As seen, in the utility model embodiment, when changing electric energy meter, use first the short clip short circuit that the secondary terminals of the current transformer of power supply is provided as electric energy meter, and then utilize line hole to block the lead that is connected with electric energy meter, so just can be in the situation that do not have a power failure the replacing electric energy meter.

Embodiment
For the purpose, technical scheme and the advantage that make the utility model embodiment clearer, below in conjunction with the accompanying drawing among the utility model embodiment, technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
The instrument that is used for live replacement of electric energy meter that the utility model embodiment provides comprises at least such as lower member:
One, short clip 6(sees also Fig. 1 a);
Short clip is used for short circuit provides the current transformer of power supply for electric energy meter secondary terminals.Need to prove, the secondary terminals of current transformer can not be opened a way, and therefore, in the utility model embodiment, uses the secondary terminals of short clip short circuit current mutual inductor.The quantity of short clip is three.
More specifically, see also Fig. 1 b and Fig. 1 c, above-mentioned short clip comprises two round mouth folders 61, and an insulated wire 62; Insulated wire 62 two ends connect respectively a round mouth folder 61.Also overlapping on the round mouth folder 61 has insulation sleeve 63, and the chuck 64 of round mouth folder is exposed to outside the insulation sleeve 63.
Two, two clamping plate 2(of flexible connection see also Fig. 2 a and Fig. 2 b).
The breach 1 that is provided with on the edge of arbitrary clamping plate 2 on a plurality of breach 1, two clamping plate 2 cooperates formation line hole 7.
In other embodiment of the utility model, above-mentioned two clamping plate 2 are connected by active connection part 3, also are provided with block ring 5 on one of them clamping plate 2.Block ring 5 is hinged by turning axle and one of them clamping plate 2.Like this, by rotation block ring 5 just two clamping plate 2 can be fixed together (seeing also Fig. 2 b).
Above-mentioned active connection part 3 can be connecting band or turning axle, as long as two clamping plate 2 can be linked together, can guarantee again that two clamping plate 2 can be opened to form certain angle and get final product.
